About Pentax HD D FA 150-450mm f/4.5-5

The HD Pentax-D FA 150-450mm F4.5-5.6 ED DC AW super-telephoto zoom lens is designed for use with Pentax K-mount digital SLR cameras. It has been developed to cover focal lengths from 150mm to 450mm - a focal-length range most demanded by high-end Pentax -camera users. It features the Pentax -original, high-grade HD Coating to produce extra-sharp, high-contrast images even under demanding lighting conditions such as in backlight. It also incorporates three ED (Extra-low Dispersion) glass elements and a super-low dispersion glass element to effectively compensate chromatic aberration. Its dustproof, weather-resistant body also makes it extremely dependable and durable in demanding outdoor conditions.

Super-telephoto coverage with three-times zoom ratio 
When mounted on a PETAX K-mount SLR camera body, this zoom lens covers a super-telephoto range from approximately 230mm to 690mm in the 35mm format. It is designed to be compact and light enough to handhold during long-range shooting of such subjects as wildlife, aircraft and sports. 

Outstanding image description 
Thanks to its state-of-the-art optics featuring three ED (Extra-low Dispersion) glass elements and one superlow dispersion glass element, this zoom lens effectively minimizes spherical and chromatic aberrations, while producing crisp, high-quality images free of color bleeding. Its MTF (Modulation Transfer Function) curve is programmed to be higher than those of conventional models in the same class to deliver high-resolution, fine detailed images. Its image circle is optimized to cover even the image size of 35mm film-format SLR cameras. As the result, it not only assures brilliant, high-resolution images without compromising the sharpness at edges even when mounted on an existing Pentax digital SLR camera body, but it is also capable of accepting future models with larger image sensors without modifications. 

HD Coating to optimize image rendition 
This lens is treated with the high-grade, multi-layer HD Coating. Compared with conventional multi-layer coatings, this Pentax -original coating assures higher light transmittance and less reflection to deliver bright, high contrast images free of flare and ghost images, even under demanding lighting conditions such as backlight. 

Dustproof, weather-resistant construction 
Developed as an AW (All Weather) model, this zoom lens features a dependable dustproof, weather-resistant construction with 21 special seals to prevent the intrusion of water and dust particles into the lens interior. By pairing it with a Pentax weather-resistant digital SLR camera body, it assures a durable, reliable digital imaging system that performs superbly in demanding shooting settings - even in rain or mist or at locations prone to water splashes or spray.
